Endurance is one of the most important flight planning considerations. That won’t change with an electric plane.

Only very large aeroplanes have the capability of dumping fuel. We’re talking Boeing or Airbus 33o. Not even a Boeing 737 or Airbus 320 has fuel dumping capability. General aviation planes certainly do not have it.

The E-Fan dramatically improves safety by totally eliminating flammable aviation fuel from the equation. Fewer combustibles onboard an E-Fan significantly reduces the risk of injury or death for pilots, passengers, first responders and others.

Because the Saturn V was a crash program and is now 50 years old. Starting from scratch at this point would yield a more efficient and less costly vehicle.

That’s an enduring myth, but a myth nonetheless.

They did not lose the plans. That is a myth. They are still stored in multiple locations, including the US National Archives.

The mill doesn’t have to be that big. The propulsion requirements for climbing out of a gravity well and for transferring from orbit to orbit are rather different.

Came to see this comment. Left satisfied.

Speaking as a Swede who has lived in the US for many years, the cultural difference when it comes to nudity is huge. In Sweden you’d think nothing of being in the sauna naked with (also naked) members of the opposite sex, for example. It’s just not a big deal.

If the US military can't retain the A-10, perhaps the powers that be can be convinced to procure a boatload of Su-25s for cheap. :)

Maybe not quite VTOL seeing as the plane appears to be moving forward beyond the deck. STOL perhaps?

As others have said, fly responsibly. As a pilot (of planes, not drones), my fervent wish is that all drone flyers make an effort to learn at least the basics of airspace rules. Even if the airspace is uncontrolled that doesn’t mean there isn’t a responsibility to “see and avoid” other traffic. It is hard enough to…

Not sure if TT3D - Closer to the Edge came out in IMAX. Definitely worth a watch in any case.

Carefully.

It is IKEA, not Ikea. IKEA is an acronym for Ingvar Kamprad Elmtaryd Agunnaryd after the founder's name, the farm where he grew up and his hometown.

If memory serves it is a drogue chute system which collects airspeed data. The data is used to calibrate the airspeed indicators.

In countries like the UK and Germany, or in Hong Kong, the attitude towards selling alcoholic beverages is much more "lax" than in most of the US. While these places have a legal drinking age* and they do check, there's not the same obsession with it that I found in the US. In my experience the number of teens…

If they're feathered, each screw acts as a speed brake, a maneuver known as a "crash-back.
